Sidewall Venting The Peerless WV - DV is designed and built to be vented through a side wall of a building using a stainless steel concentric vent terminal ( 4 inch diameter tube inside an 8 inch diameter tube ) . Exhaust gases from combustion contain water vapor . During the cooler months of the year , this water vapor will condense into a visible vapor plume . This water vapor may condense on any surface near the vent terminal . Care must be taken not to locate the vent terminal where the exhaust gas , vapor plume and condensation could cause a hazard or a nuisance . Do not locate terminal under a deck , for instance , as it may create a coating of ice on the deck during the winter months , as well as shorten the life of the deck materials . Refer to Chapter 4 in this manual for specific terminal location requirements . Condensate from a side wall vent terminal may also cause paint on surrounding surfaces to crack and peel . If the boiler is used to heat potable ( tap ) water , the boiler will cycle year round . The effects of hot exhaust gases and odors must be taken into consideration during summer months . Side wall vented , oil fired appliances may cause soot staining on wall surfaces surrounding their terminals . To reduce the potential for staining , the boiler must be serviced annually . Soot and scale must be completely removed from the combustion chamber and cast iron heat exchanger flueways . See Chapter 7 in this manual . The oil burner must be completely serviced and set up according to the specifications shown in Chapter 5 of this manual . Page: 4

Read carefully , study these instrudions before beginning work . It will save time . Study the included drawings . Save these instructions for reference . This boiler must be installed by a qualified contTactor . The boiler warranty can be voided if the boiler is not installed , maintained and serviced correctly . in all cases . Authorities having jurisdiction shall be consulted before installations are made . NEVER BURN GARBAGE OR PAPER IN THE UNIT , AND NEVER LEAVE COMBUSTIBLE MATERIAL AROUND IT .

Make up cold water supply connection to the boiler . 3 . Plug all open tappings in the boiler and fill with water . Apply approximately thirty ( 30 ) psi pressure . Check to make certain that all joints and fittings are water tight . 4 . After all joints and connections have been proven water tight , remove cold water supply and plugs from all tappings that are to be used . See page 13 , Figure 10 for tapping locations . 5 . Relurn water piping must be done in such a manner to allow clearance from the burner mounting plate to Figure 2 the circulator stand pipe or other piping when opening and closing the burner mounting plate . Peerless Heater Company suggests using a 1 - I / 4 " Note : If boiler is to be used in conjunction with a refrigeration tee , a 90 Â° street elbow and 1 - 1 / 4 " x 3 - I / 2 " pipe system , the chilled medium shall be piped in parallel with nipple in the return tapping before a vertical boiler and proper valves applied to prevent the chilled medium from entering the boiler . Refer to Figure 2 . circulator stand pipe is used as shown in Figure 10 on Page 13 . When the boiler is connected to heating coils located in air handling units , the boiler piping system must be equipped with flow coni _ ol valves or other automatic devices to prevent gravity circulation of the boiler water during the cooling cycle . Figure 1 6 . The supply and return connections should be sized to suit the system . A I - 1 / 2 " to 1 - 1 / 4 " reducing coupling may be used on the return where the system piping is 1 - 1 / 2 " . The supply should be out of the top of the back section and return to the bottom of the front section . There is a 3 / 4 " tapping in the top of the back section for air eliminafion . Page: 9

4 . Remove any scale or soot from the combustion chamber area by vacuum cleaning or any other available means . Boiler is to be cleaned at least once a year . To thoroughly clean the boiler it must be brushed Combustion chamber cover plate must be opened down from the top . Alternately , for limited space or to facilitate this operation . minimum clearance to combustible installations , cleaning the heat exchanger from the combustion chamber side is acceptable . 5 . Replace oil burner and flue collector cover plate making sure all gaskets are in place . TO CLEAN : 1 . Turn off all electrical power to the boiler before beginning cleaning operation .
